The Japanese do not still attack or persecute anyone, unlike the Turks do to Christians.
But if the japs actually argued that the rape of Nanking was well-deserved and the fault of the Chinese then the US certainly should take a stand against them. So really it isn’t remotely the same thing. One nation denies atrocities and another *defends* the atrocities as the right thing to do...
In any event the US is more important to the Turks than Turkey is to the US. Why shouldn’t the Turks worry about upsetting the US rather than the other way around? Consider this payback for their lack of support recently.
Do you wish to elaborate on that?
